Abstract
PURPOSE: This article addresses the complex clinical scenario where patients present to otolaryngologists with symptoms typically ascribed to chronic rhinosinusitis (CRS) or migraines which may in fact stem from elevations in intracranial pressure. We aim to clarify the diagnostic challenges and emphasize the importance of considering elevated intracranial pressure (eICP) as its symptoms overlap with both CRS and migraines. METHODS: This narrative review synthesizes clinical experiences and literature to discuss the differential diagnoses involving CRS, facial pain/pressure, migraines, and eICP. Key discussion points include symptomatology of eICP and its management in otolaryngological practice. RESULTS: Patients presenting with symptoms of CRS or migraine may exhibit overlapping signs that makes diagnosis challenging. Patients with symptoms of facial pain and pressure, or other findings such as ear fullness, muffled hearing, and tinnitus, that do not resolve with conventional topical intranasal therapies or migraine management should be worked up for eICP. CONCLUSION: The overlap in clinical presentations among patients with concern for CRS, migraines, and ICP elevations poses a diagnostic challenge. It is crucial for otolaryngologists and neurologists to collaborate closely to ensure accurate diagnoses and appropriate management. Enhanced awareness and understanding of the broader spectrum of symptoms associated with eICP can prevent misdiagnosis and promote better patient outcomes.
